Professor Lenton is a founding Director of the Global Systems Institute at the University of Exeter and Chair in Climate Change and Earth System Science. He has more than 25 years research experience, focused on modelling of the biosphere, biogeochemical cycling and climate, and associated tipping points. Tim is renowned for his work identifying climate tipping points, which informed the setting of the 1.5C climate target and associated net zero targets and nationally determined contributions. 

Tim works actively with policymakers and businesses helping them assess the risks of climate change and nature loss and highlighting the opportunities for ‘positive tipping points’ that can accelerate desired changes. Professor Lenton is currently leading a team of more than 200 people from over 90 organisations in 26 countries to produce an authoritative assessment of the risks and opportunities of both negative and positive tipping points in the Earth system and society. The ‘Global Tipping Points Report’ will be launched at COP28 in December 2023.
